2. GETTING STARTED

This chapter describes the Jackrabbit board in more detail, and explains how to set up and use the accompanying Prototyping Board.

NOTE: This chapter (and this manual) assume that you have the Jackrabbit Development Kit. If you purchased a Jackrabbit board by itself, you will have to adapt the informa- tion in this chapter and elsewhere to your test and development setup.

2.1 Development Kit Contents

The Jackrabbit Development Kit contains the following items:

•BL1810 single-board computer.

•Prototyping Board.

•Universal AC adapter, 12 V DC, 1 A (includes Canada/Japan/U.S., Australia/N.Z., U.K., and European style plugs). If you are using another power supply, it must provide 7.5–25 V DC at 5 W.

NOTE: The linear voltage regulator becomes rather hot for voltages above 15 V.

•10-pin header to DB9 programming cable with integrated level-matching circuitry.

•Dynamic C CD-ROM, with complete product documentation on disk.

•Getting Started instructions.

•A bag of accessory parts for use on the Prototyping Board.

•Screwdriver.

•Rabbit 2000 Processor Easy Reference poster.

•Registration card.
